The new ads will launch on Tango — among other partners — with in-stream posts that look like other Tango updates, but feature a small ‘sponsored’ mark in the upper corner. Native ads are fairly hot at the moment, with most social networks looking to fuse them with their core timelines or feeds in some manner. Because they’re less jarring and easier to pass off as ‘content’, they’re being treated as the next big thing for focused mobile experiences like those found in apps like Instagram. These in-stream ads will be presented by the apps themselves, templated to match their surroundings, but served up by MoPub.
